A series of discounts from the list price are offered. They are 35%, 3%, and 2%. Calculate the final price
for a series of prices starting at $100 and continuing at $110, $120. etc. 35% is equivalent to .65; 3% to
.97; and 2% to .98. The initial price call (A)

Answer 4 is the original price of $100 plus the increment of $10. The next time COMP is pressed, A =
is displayed. By-pass placing a value in for A each time as it has been changed automatically by equation 4.
Answer 3 will now give the discounted price for a list of 110. Continued pressing of the IcompI button will
give the answer for each increment of 10 of the price. After putting the initial value of A in at 100, it is
unnecessary to key in any other values.
